td_disconnect · Td MCP: Risk & Policy

WHAT IT DOES

What td_disconnect does on Td

AI agents use td_disconnect to create or update resources in Td — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Td environment.

WHY IT NEEDS A POLICY

Why td_disconnect needs a policy

This tool modifies TouchDesigner's operator graph by removing connections between operators. While reversible (can reconnect), it changes the active state and dataflow of the system. Not Destructive because reconnection is straightforward and no data is permanently lost. Not Execute because it doesn't run arbitrary code or trigger computation—it only manipulates graph structure.

From the tool's definition Tool disconnects an operator's connector, modifying the topology/configuration of TouchDesigner operators. The description 'Disconnect an operator's connector' indicates a state-changing operation that alters operator linkages.

Verdict

td_disconnect Rate-limited

td_disconnect stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Td, so you can run agents against it safely.

FAQ

Questions about td_disconnect

What does the td_disconnect tool do? +

Disconnect an operator's connector. It is categorised as a Write tool in the Td MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on td_disconnect? +

Register the Td MCP server in PolicyLayer and add a rule for td_disconnect: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Td. Nothing to install.

What risk level is td_disconnect? +

td_disconnect is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit td_disconnect? +

Yes. Add a rate_limit block to the td_disconnect rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block td_disconnect completely? +

Set action: deny in the PolicyLayer policy for td_disconnect. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides td_disconnect? +

td_disconnect is provided by the Td MCP server (tai5863/td-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
